Answer to Question 1

ANS: B
The pressure-release valve allows some of the gas on top of the liquid to escape if the contents are warmed too much. This release of gas allows the gas within the container to expand, thus lowering the temperature. This maintains the gas under pressure between its boiling point and its critical temperature so that the majority of the reservoir's contents will be maintained in the liquid state.

Answer to Question 2

ANS: D

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
